I have a 170A battery paired with a large-sized BMS that I purchased in 2022. Recently, I obtained a 15A parallel module but I'm having trouble finding the appropriate connection point for it on the BMS. Specifically, the module has a black wire with a small connector featuring two wires—one black and one red. However, there doesn't seem to be an available spot for this on my current BMS setup. Additionally, I'd like to connect a 3-inch display to the BMS, but I'm uncertain about where to attach it. I would greatly appreciate your guidance on how to connect both the parallel module and the display to ensure proper functionality of my battery system. Prompt assistance would be fantastic, as I'm eager to get my battery operational. Thank you!
